I never had any acne as a teen, but once I hit about 35 and my hormones started shifting, I developed what is called "adult onset acne." Mine is cystic, which means it gets incredibly painful. So bad, that I am actually taking BC to control the bacteria levels in my skin. I don't NEED the BC as I had a hysto in 2002, so it's weird to take it for my skin, especially as I always had really clear skin.
As far as the wrinkles go, bring 'em on. They tell a story, and I see no reason to worry about them.
